Answer:
x = 20°
f = 40°
Step-by-step explanation:
4x + 5x = 180°
because a straight line is 180°
so 9x = 180°
1x = 180 ÷ 9
1x = 20
all angles in a triangle add together is 180°
so 7x + f = 180°
1x = 20
7x = 20 × 7
7x = 140°
f = 180° - 140 °
f = 40°
Answer:
F, K & G
Step-by-step explanation:
Points are colinear if they lie on the same straight line.
only K , F & G line on a straight line.
Answer:
they are corresponding angles
